Ceramic Coated Headers for GM LS Trucks & SUVs 2002-2013

Ceramic Coated Headers – 2002–2013 GM LS Truck & SUV 1-5/8" Primaries

Upgrade your compatible GM LS-powered truck or SUV with Certified Automotive Experts Ceramic Coated Headers, engineered as a direct replacement for restrictive factory cast-iron exhaust manifolds. Designed for select Chevrolet, GMC, and Cadillac full-size trucks and SUVs, these performance exhaust headers combine improved exhaust flow, durable 304 stainless steel construction, and high-temperature ceramic coating for long-lasting protection.

These Ceramic Coated Headers feature 1-5/8-inch mandrel-bent primary tubes designed to provide a smoother exhaust path compared with restrictive factory manifolds while maintaining factory-style fitment. The 304 stainless steel construction provides excellent durability and corrosion resistance, while precision TIG-welded seams and 3/8-inch thick laser-cut flanges help provide a secure, reliable connection at the cylinder heads.

The high-temperature ceramic coating is designed to help manage exhaust heat, reduce surface corrosion, and protect nearby engine-bay components. This makes these ceramic headers a practical choice for daily-driven trucks, work vehicles, towing applications, restoration projects, and LS performance builds where heat management and durability are important.

GM LS Header Fitment

These LS headers are designed for select Chevrolet, GMC, and Cadillac full-size trucks and SUVs equipped with compatible LS-based V8 engines from the 2002–2013 model-year range.

They are designed around factory-style cylinder heads and exhaust configurations for a straightforward bolt-on replacement where the original exhaust manifold is worn, damaged, or restrictive.

Important Passenger-Side Flange Information

The passenger-side outlet uses a ball-and-socket beveled flange designed to connect to factory Y-pipes that use a donut-style gasket.

This configuration is commonly found on compatible 2002–2013 GM LS truck and SUV applications. However, some vehicles may use a flat flange on the passenger side.

Vehicles equipped with a flat passenger-side flange are not compatible with these headers.

Always inspect your factory Y-pipe connection and verify the flange style before ordering.

Ceramic Coating Benefits

The ceramic coating on these Ceramic Coated Headers is designed to provide additional protection in high-temperature exhaust environments. Compared with uncoated steel headers, the coating helps protect the header surface from corrosion while helping manage radiant exhaust heat.

This makes them particularly useful for applications where exhaust temperature, engine-bay heat, and long-term durability are important, including:

• Daily-driven trucks
• Work trucks
• Towing vehicles
• LS performance builds
• Classic and custom truck projects
• Exhaust manifold replacements

Construction & Performance

The 1-5/8-inch primary tubes are mandrel bent to maintain consistent tubing geometry and provide an efficient exhaust path. Compared with restrictive factory cast-iron manifolds, the header design is intended to improve exhaust flow while maintaining a factory-style installation approach.

The 3/8-inch thick laser-cut flanges provide a solid mounting surface, while TIG-welded seams help deliver dependable structural strength for long-term use.

Applications

These Ceramic Coated Headers are suitable for compatible:

• Chevrolet full-size trucks
• GMC full-size trucks
• Cadillac full-size SUVs
• GM LS-powered trucks and SUVs
• Daily-driver applications
• Work trucks
• Towing applications
• LS performance builds
• Factory-style exhaust replacements

Important Fitment Information

These headers are not compatible with:

• 1999–2001 GM trucks
• 2014 and newer Gen V LT-series engines
• Vehicles using a flat passenger-side Y-pipe flange

Before purchasing, verify:

1. Your vehicle's model year
2. LS engine configuration
3. Cylinder-head configuration
4. Passenger-side Y-pipe flange style
5. Factory exhaust connection
6. Overall header clearance

Because GM used different exhaust configurations across certain model years and applications, vehicle year alone should not be used as the only fitment check.

Frequently Asked Questions

What are Ceramic Coated Headers?

Ceramic Coated Headers are performance exhaust headers finished with a high-temperature ceramic coating designed to provide heat management and corrosion protection while replacing restrictive factory exhaust manifolds.

What engines do these headers fit?

These headers are designed for select GM LS-based V8 applications in compatible Chevrolet, GMC, and Cadillac trucks and SUVs from 2002–2013.

What size are the primary tubes?

The primary tubes measure 1-5/8 inches and feature a mandrel-bent design.

What are these headers made from?

The headers are constructed from 304 stainless steel with TIG-welded seams and 3/8-inch thick laser-cut flanges.

What is the benefit of the ceramic coating?

The high-temperature ceramic coating helps manage exhaust heat, reduce surface corrosion, and protect nearby engine-bay components.

Are these direct-replacement headers?

Yes. They are engineered as a factory-style replacement for compatible cast-iron exhaust manifolds and are intended for straightforward installation when all fitment requirements are met.

Will these headers connect to my factory Y-pipe?

The passenger-side outlet is designed for factory Y-pipes using a ball-and-socket beveled flange with a donut-style gasket. Some vehicles have a flat passenger-side flange, which is not compatible.
